使用非线性调频信号不但可以有效地解决探测距离和分辨能力的矛盾,而且可以使压缩波形的固有旁瓣很低,所以非线性调频信号是一种非常重要的雷达脉冲压缩信号。考虑到现有设计非线性调频信号的方法计算量很大,本文提出了一种设计非线性调频信号的新方法,其计算量只是现在设计方法的几千分之一,从而使利用普通微机设计非线性调频信号成为可能。
The use of non-linear FM signals not only can effectively resolve the contradiction between detection range and resolving power, but also can make the inherent side lobes of the compressed waveform very low. Therefore, the nonlinear FM signal is a very important radar pulse compression signal. Considering that the existing methods for designing nonlinear FM signals are computationally intensive, a new method of designing nonlinear FM signals is proposed in this paper. The computational load is only a few thousandths of that of current design methods, so that the common microcomputer design Non-linear FM signal becomes possible.
